VMB1TC Temperature controller manual – rev 5.0

Allocate a relay channel to control valve 1
When room temperature drops below the desired value, the temperature sensor sends a request on the bus to energize a
relay. When the room temperature rises above the desired value, another request by the temperature sensor is
transmitted over the bus to de-energize the relay.
In our example, the first temperature sensor must control relay channel 3 of the first relay module to steer the valve.
1. Set the first sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.
2. Set the MODE and TIME1 rotary switches for
channel 3 of the first relay module to ‘0’ (instant
control).
3. Remember the address of this relay module to
reinstate it later on.
4. Set the address of the first relay module to ‘C3’.
The ‘MODE 3’ LED flashes to indicate push button
learning mode (PBM).

and the red LED on the sensor module flashes.

original value.
